Lectrosonics DPR-A, Digital Plug-on Transmitter

Lectrosonics DPR-A, Digital Plug-on Transmitter

This Lectrosonics DPR-A is a unique plug-on transmitter design and perfectly ideally match in any microphone or line level source via a standard XLR connector. The Lectrosonics DPR-A can tune in 100 kHz or 25 kHz steps across the UHF television band from 470.100 to 607.950 MHz, with a selectable output power of 25 or 50 mW. The purely digital architecture utilizes AES 256-CTR encryption for high level security applications. The external antenna provides exceptional operating range. Also, the Lectrosonics DPR-A transmitter is specially designed with high efficiency digital circuitry for extended operating time on two AA batteries, with status indicated by a multi-color LED. An IR (infrared) port is included to simplify setup with IR enabled receivers. Updates can be made via SD card. The input amplifier of the Lectrosonics DPR-A uses an ultra low noise op-amp for quiet operation. It is gain controlled with a wide range, dual envelope limiter, providing over 30 dB of headroom above full modulation. A 24-bit A-D converter digitizes the audio, then filters out supersonic noise above 21 kHz.
